The present invention relates to chair head rests of the character used in connection with barber chairs and the like.

he object of the invention resides in the provision of a head rest having a wide range of adjustment, and capable of being quickly and conveniently arranged in any desired position for the comfort of the user.

Another object of the invention resides in the provision of a head rest capable of being easily adjusted to the desired position, or wholly disposed in an out of the way position when not in use, thus eliminating the necessity of removing the head rest from the chair, as is now custommy` The invention also contemplates a head rest which is simple in construction, including a paper roll, and a novel construction of means for clamping the paper over the head rest.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals of reference indicate similar.

parts in the several views and wherein:

Figure 1 is a side elevation of the head rest,

Figure 5 is a fragmentary View showing how the springs and paper roll are supported by the frame of the head rest.

Figure 8 is a fragmentary view of one of the springs.

Referring to the drawings in deban, 1o indicates a shank upon which the head rest is mounted, and this shank is provided with a series of openings 11 so that the shank can be adjusted vertically on the chair (not shown) in the usual manner. The upper end of the shank is slightly thickened as at 12, and characterized with a notched segment 13 for a purpose to be hereinafter described.

The head rest proper comprises an open frame4 of substantially rectangular contour in plan, but

which is curved transversely as illustrated. The opposed end members 14 of the frame are pro- .vided with aligned slots 15, each slot having communication with a recessed portion 16. .The corresponding slots of these end members receiveGQ the adjacent ends of coiled springs 17, each spring having its outer convolutions extended as at 18, as illustrated in Figure 8. These extensions 18 are receivedby the slots 15, and hold the springs associated with the frame, but in a manner where- G5 by any one or more springs can be conveniently removed, and replaced by a new spring as the occasion may require. These springs support a pad 20 which may be constructed in any suitable manner and from any suitable material. Also supported by the end members 14 of the frame is a transverse shaft 21 upon whichr is' mounted a paper roll 22, the paper being unwound from the roll and extended over the pad` 20, and passed downwardly between the pad and 75v the rear member 23 of the frame. The paper is clamped to the rear 'member 23, preferably by means of a plate 24, which is substantially coextensive in length with the rear member 23 of' the frame. This plate is carried by arock shaft 25 which is journaled between the end members 14 vof the frame and provided with springs 26 which `normally maintain the plate 24m clamping position. The shaft 25 is equipped lwith. a

thumb engaging member 2'?, so that the shaft 85.

25 can be quickly and conveniently manipulated to release the paper from the clamping plate .24. The shaft 21 can be removed from the frame when desired, asr it is slidably received by aligned openings in the end members 14. One end of the shaft 21 is provided with a head 28 adapted to lie fiush with the outer surface of the adjacent end member 14. as shown in Figure 5, and held immovably associated with the frame by means of a plate 29. This plate is pivoted on the end member 14 and can be easily swung to either its active or inactive position. In other words the plate 29 can be swung to uncover the head 28 of the shaft 21 so that the latter can be easily removed from the frame.

The front member 30 of the frame is provided with spaced depending apertured lugs 31 which receive a bolt 32 which is pivoted in the thickened end portion 12 of the shank. Consequently the head rest is mounted for pivotal adjustv ment on the shank, so that the head rest can be arranged at any angle with relation to the shank l0 for the comfort of the user. The head rest automatically cooperates with the grooved segment 13 to hold itself fixed with relation to 110.-.

the shank in its given position for use. For this purpose the front member supports a hingedly mounted latch 33 from the under side of which depends a finger 34 which slides through an opening 35 in the front member 3G of the frame. Pivotally connected with the free end of the latch 33, as at 36, is a headed pin 37 which slides through an opening in the front member 30 of the frame. Surrounding this pin is a coil spring 38 which bears against the frame and head of the pin to normally maintain the latch 33 in its active position.

In practice, the shank 10 can be adjusted vertically with relation to the chair, upon which the head rest is used in the ordinary well known manner, while the head rest proper can be swung upon its pivot 32 to occupy any desired angle with relation to the shank 10 for the comfort of the user. It is only necessary to press inwardly on the headed pin 37, whereupon the latch 33 is ele- Vated and the finger 34 removed from the grooved segment 13. Under these conditions the spring 38 is compressed and placed under tension. After the head rest has been adjusted to the desired position, the pin 37 is released, whereupon the spring 38 automatically returns the latch 33 to its active position, with the finger 34 received by the adjacent groove of the segment 13. When use ofthe head rest is not necessary, it can be swung upon its pivot to` occupy an out of the Way position as clearly illustrated by dotted lines inFigure 1. In this position the head rest is wholly arranged at the rear of the standard 10 and suspended from the upper end thereof, thereby eliminating the necessity for removing the head rest from the chair as is customary with present day constructions.

The paper can be also easily unwound from the roll 22 and clamped against the rear member 23 of the frame, and released therefrom by manipulating the thumb engaging member 27. The structure in its entirety comprises a minimum of parts and can be quickly and conveniently manipulated for the purpose intended.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily understood, I desire to have it known that I do not limit myself to what is herein illustrated or described -and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What is claimed is:

1. In combination, a shank, a grooved segment supported by the upper end thereof, a head rest including a frame pivotally mounted on the upper end of the shank and capable of being arranged at any desired angle thereto for use, a latch hingedly supported on the frame and including a nger slidable through an opening in the frame to engage said segment, a headed pin pivotally connected with the free end of the latch and slidable through an opening in the frame, and a coiled spring surrounding said pin and normally maintaining the latch in its active position.

2. In combination, a shank, a grooved segvment supported by the upper end thereof, a head rest includingva frame pivotally mounted on the upper end of the shank and having spaced openings in the lowerrnost member thereof, a latch plate hingedly mounted on said member and normally arranged parallel therewith', a nnger de-A pending centrally from said plate and passed through one of said openings in said member to engage said segment, and yieldable means connected with the free end ofthe plate and slidable through the other of said openings of themember to normally maintain said ringer engaged with said segment.

3. In combination, a shank, a grooved segment supported by the upper end thereof, a headrest including a frame pivotally mounted on the upper end of the shank and having spaced openings in the lowerrnost member thereof, a latch plate hingedly mounted on said member and normally arranged parallel therewith, a finger depending centrally from said plate and passed through one of said openings in said member to engage said segment, a headed pin pivotally connected with the free end of said latch plate and slidable through the other of said openings ofthe member, and a coiled spring surrounding said pin and interposed between the head of the latter and said member to normally maintain the nger of said latch plate engaged with said segment.
